What is the Austin Chalk formation?  The Austin Chalk formation stretches across numerous fields in Texas, Louisiana and a small portion of Mississippi.  The Austin Chalk is currently producing Natural Gas and Oil.  Companies drilling the Austin Chalk are having huge success and are also finding other oil & natural gas rich zones such as the Eagle Ford Shale.  The Austin Chalk formation reaches 500 km in length and 50 km in width.   The first wells drilled in the Austin chalk were drilled in the 1920’s.  Initially, vertical drilling was the only technique used to reach the Austin Chalk reservoirs, but as horizontal drilling came about, they changed the primary technique as horizontal drilling significantly enhanced the productivity of the wells by intersecting multiple fracture sets.  Austin Chalk ranges in thickness from 15 to 180 meters. It lies just above the Eagle Ford shale, yet below the Dessau formation.  The average targeted depth is roughly 1700 meters.   

The Austin Chalk formation can be found in the following counties in Texas:

Fayette County, Washington County, Burleson County, Brazos County, Grimes County, Montgomery County, Gonzales, Wilson, Karnes, Grayson County, Limestone County, Bell County, Silliamson County, Travis County, Medina County, Uvalde County, Bexar County, fayette County, Lee County Texas, Colorado County, Austin County, Milam County, Robertson County, Jasper  County and Newton County 

The Austin Chalk formation can also be found in the Vernon and Rapides Parishes of Louisiana.   The Austin Chalk formation in Texas continues to yield great results.  This will continue into 2013/2014.

Companies Drilling in the Austin Chalk Formation - Austin Chalk Stocks

EV Energy Partners (EVEP) continues to be active in the Austin Chalk.  Now I’ll move to the Austin Chalk where EVEP holds a 13% to 15% working interest.

During the first quarter of 2012, we finished drilling one well and drilled a second well. Three new wells began producing during the quarter. We plan to drill nine wells in 2012. The multi-stage hydraulic fracturing process is working quite well in the Chalk. Our last two wells are producing above expectations.

One had initial production of 550 barrels of oil per day and the other had 6 million a day of gas with 130 barrels a day of oil. About half of the 2012 program in the Chalk will utilize the multi-stage process. And we are evaluating an opportunity to deploy this technology on more of our Austin Chalk acreage.

Swift Energy Co. (SFY) -   Swift Energy SFY Austin Chalk Formation - In the Company's Central Louisiana/East Texas core area, one operated well and one non-operated well were drilled, both targeting the Austin Chalk formation in the Burr Ferry field in Vernon Parish, LA.

The GASRS 16-1 well, a non-operated well, was completed in the Austin Chalk and had an initial production rate of 207 bbls/d of oil and 1.3 MMcfg/d with flowing casing pressure of 1,250 psi on a 25/64" choke. This well, drilled near the southern extent of the Company's joint operating area, encountered fewer natural fractures than the wells drilled farther north have encountered. This well is important in understanding the geology in the area, which is essential to future development plans.

The Swift Energy operated GASRS 20-1 finished drilling operations during the third quarter and was completed in the Austin Chalk. A mechanical problem occurred during the initial cleanup of the well that required a workover rig to resolve. A workover rig is currently on this well and work is underway to remedy the issue. This well bore remained in zone for the extent of the 4,254 foot lateral and encountered high natural fracture density and strong tubing pressure.

Lucas Energy (LEI) - Lucas Energy, Inc. (NYSE Amex:LEI) an independent oil and gas company (the "Company" or "Lucas"), today announced that the Company has completed the Hagen Ranch Unit No.1HST well in Gonzales County, Texas as a flowing horizontal oil well in the Austin Chalk formation. The official 24 hour test that will be reported to the regulatory agency is 351 BOPD (barrels of oil per day), and 86 BWPD (barrels of water per day) with 419 psig (pounds per square inch), pumping. Lucas has an approximately 64% working interest in this well.

Although the well is pumping (artificial lift), it continues to flow up the casing side as well as the tubing. The Company drilled a new lateral in the Austin Chalk formation from an existing well bore. There are now three wells completed as new laterals from existing well bores; however, the Hagen Ranch Unit No.1HST well is the most promising of the three, showing signs of virgin pressure from previously untapped reserves, as did the recently completed Hagen Ranch No.4 well.

William A. Sawyer, President and Chief Executive Officer of the Company said, "We believe that the results of Lucas' drilling program throughout this fiscal year, including our recently drilled wells, continue to prove our theory that the Austin Chalk is undervalued."

Evolution Petroleum EPM -  Evolution Petroleum (EPM) is active in the Austin Chalk Field - The company drills for oil & gas in Grimes County, TX.

Anadarko Petroleum  APC - Austin Chalk:  Drilling activity continued with four operated rigs. Anadarko spud eight wells.  During the quarter, the company spud the eleventh well of a 25-well planned re-entry program in the Northstars field, with encouraging results.

GeoResources GEOI - As previously announced, in February 2012, the Company closed on a $40.4 million acquisition (subject to customary purchase price adjustments) of producing Austin Chalk properties in the Brookeland Field area of east Texas in Jasper and Newton counties from an unaffiliated third-party effective January 1, 2012. With the effective date of this purchase as of January 1, 2012, and the transaction closing on February 28, 2012, net production, revenue and cash flow associated with this property for January and February were credited to the capitalized purchase price of the property. Accordingly, the Company only recorded production related to this property for the month of March 2012.

The Company also recently completed its first operated Austin Chalk well on its Eagle Ford acreage position in Fayette County, Texas, the Rightmer #2HRE (50% W.I.). This well averaged 339 boe/d (93% oil) over its first five days of production.

Abraxas Petruleom (AXAS) - In the Jourdanton area also in the Eagle Ford Shale where Abraxas has a 100% working interest, we recently a commissioned a 22 square-mile 3D seismic survey which we will use to help evaluate the Eagle Ford, the Buda and the Austin Chalk under our acreage.

US Energy (USEG) - U.S Energy (USEG) currently drills for oil & gas in the Austin Chalk - At September 30, 2012, the Company had participation in 79 gross or 14.88 net producing Wells, which include 62 gross Williston Basin Wells, three Gulf Coast Wells, 11 gross Austin Chalk Wells, and three gross Eagle Ford Wells.

Clayton Willaims Energy (CWEI) -  In the Giddings area, where we have the Austin Chalk and Eagle Ford opportunities, which Clayton will talk a lot more about here in a moment, that’s mostly held by production. And even though we do plan to drill some more Eagle Ford tests, we’re not pushed there to run rig. So we’re in a great position

Forest Oil (FST) - Forest Oil (FST) comments on the Austin Chalk formation - I think that we are going to see contribution from the Austin Chalk simply because there has been vertical chalk producers drilled in areas across this acreage position, and so we know that chalk contributes. Our microseismic results taken from upper Eagle Ford completions, showed growth up into the chalk, so there's no reason for me not to expect that we're going to get a contribution there.
